measuring performance in PHP - how?

[davidklonski]

Hello

I would like to test how fast my PHP scripts are executed.
I was thinking of calculating the current time (if millis - if possible) at the beginning of the script (server side) and to send that value into a javascript variable.
When the page loads (onload() event), I calculate again the the current time in javascript and just subtract the latter from the first.

I am hoping that this will give me the time in millis from the moment the page reached the server until the time it was loaded in the client.

Does anyone know of a way to obtain the current time in millis?
Does anyone know of a better way to calculate performance?

thanks

i think your general theory here is right, that would time from the start of execution to the end of display - but you'd need to get the time var from php to javascript, and then use dhtml to calculate the final time (as the page has loaded already)

when i set up my last site, i saw no point in timing display - as you cannot make amends for people having poor connections, so i just stuck to timing execution.

i started with an article by Allan Kent right here on phpbuilder and took things from there...
